Longer Lasting Lubrication
Automakers are striving for extended warranties,
expecting longer intervals between vehicle service
visits and very limited relubrication operations. Krytox™
lubricants have provided state-of-the art performancefor mechanical systems, such as gearboxes, bearings,
chains, seals, actuators, valves, and other components.
Krytox™ lubricants don’t oxidize; they provide excellent
lubricity and a high viscosity index through a broad rangeof viscosity grades. Most applications where Krytox™
lubricants are specified are considered by OEMs to be
lubricated for the expected lifetime of the vehicle.

Performance Lubricants

The Right Choice for Your Design Challenge
Krytox™ oils and greases are based on
perfluoropolyether (PFPE) oils, with a full range ofviscosities available. These synthetic fluorinatedlubricants are effective from -75 °C to greaterthan 400 °C (-103 to >752 °F), depending upon
operating conditions and product grade.

Krytox™ performance lubricants have properties that reduce impact on the environment:• Krytox™ products are fully synthetic—not petroleumbased—and totally inert, so Krytox™ oils and greases
do not react with anything in the environment. Unlike
other lubricants, at temperatures under 350 ºC(662 °F), Krytox™ oil does not oxidize or break down
into other substances that could be harmful.
• Krytox™ lubricants do not contain any volatile organic
compounds (VOCs), according to the U.S. EPA
definition. Our full fluorinated lubricants are made offluorine, oxygen, and carbon only.
• Krytox™ products have a very long service life. Thismeans that products do not have to be replaced anddisposed of frequently, which reduces waste.

• Because the Krytox™ molecule stays intact, theoils can be recycled if they become contaminated.
The recycled products can then be returned to thecustomer for reuse.
• Krytox™ oils and greases are not consideredhazardous wastes as manufactured under theU.S. EPA Resource and Recovery Conservation
Act guidelines. However, treatment, storage,transportation, recycling, and disposal of theseproducts must be in accordance with applicable
federal, state/provincial, and local regulations.

The Right Choice for Our Environment
Protection of the environment and people is acore value of Chemours. Our sustainability goals
go beyond traditional footprint reduction to
include goals that tie our business growth to thedevelopment of safer and environmentally improved
new products and sustainable solutions.
Krytox™ lubricants provide longer lasting lubrication,
which lowers the frequency of relubrication;
therefore, reducing the use of materials and reducing
waste—important steps in helping to reduce productimpact on the environment.

Effective Over a Wide Temperature Range
Krytox™ greases typically last 5-50 times longer thanstandard greases. One common bearing test that
demonstrates the extreme performance of various
grades of Krytox™ grease is the ASTM D-3336 test
method, where heating/cooling test cycles are continued
until failure or the completion of a specified number ofhours of running time.
Test results have shown that Krytox™ greases cancontinue to perform beyond thousands of hours andat temperatures beyond the range specified for mostapplications—even outlasting the tester itself.

Compatibility with Elastomers and Plastics

Compatibility with Metals

Krytox™ performance lubricants are compatible withthe following common elastomers and plastics, aswell as many more:

Because of their low surface tensions, Krytox™ oils
and greases easily lubricate metallic surfaces. Krytox™
lubricants are chemically inert and, therefore, haveno adverse effect on metals when the temperature isbelow 288 °C (550 ºF).

Krytox™ Performance Lubricants for Noise, Vibration,and Harshness
Within an automobile’s interior, there are several places
where different materials contact each other. Some
examples include metal on plastic, leather on leather, andweather-stripping. Movement between these surfaces
often results in a series of noise described as squeak, itch,or judder. Krytox™ lubricants can permanently eliminate
these noises. They are easy to apply, have low volatility,
and can remain in place over the vehicle’s entire lifetime.
Furthermore, Krytox™ oils and greases are compatible witha wide variety of materials, and have the frictional andlong-life characteristics that make them ideal lubricants inthese applications.
Krytox™ Performance Lubricants for Automotive
Underhood Applications
Fan Clutch
A thermostatically controlled fan clutch typically drives
the cooling fan. The bearings that support the drive shaft
for this clutch regularly experience high temperatures. If
these bearings wear and begin to fail, the cooling fan runs
6less efficiently. When this occurs, the engine can overheat,
and any resistance in fan clutch rotation can drain valuable
power from the engine’s drive shaft, further reducing overallperformance. Krytox™ lubricants have low volatility anda high viscosity index, providing long-life and excellent
lubrication to the fan clutch bearing under these hightemperature conditions.
O-Ring Lubrication/Assembly Lube
O-rings effectively seal many interfaces in an automobile.
A lubricant is often applied to keep seals in place duringassembly and allow them to assemble without damage.
Choice of lubricant is critical: if the wrong lubricant isused for a given seal material, the seal could degrade,prematurely causing serious damage. Krytox™ lubricants
are the preferred choice because they are compatible withall seal materials. Furthermore, Krytox™ lubricants do notcontribute to seal degradation, because they do not oxidize,and they have greater temperature stability than the seals.
Alternator
The alternator is usually belt-driven by the engine andsupplies electricity to basic automobile functions

Fan Clutch(headlights, radio, etc.) while recharging the car battery.
As the electricity is being generated, the alternators, andhence the bearings, get very hot. Standard lubricantsvolatilize in the extreme high temperature environment of
the alternator, leading to alternator bearing failure.
As the bearings wear and begin to fail, they can increase
the alternator’s resistance to rotation.
This reduces the alternator’s performance and robs
performance from the rest of the automobile.
Perhaps more critically, if the alternator bearings fail,the alternator will fail and the vehicle will stop running.
The higher output alternators used in today’s vehicles
generate a tremendous amount of heat, demanding theadvanced, reliable performance and heat stability of
Krytox™ lubricants.
EGR Valve
The exhaust gas re-circulating (EGR) valve reduces
nitrogen oxide (NOx) emissions formation by
re-circulating some of the exhausted gas back into theengine cylinders. This lowers the peak temperaturesinside the cylinder; thus, reducing the rate of NOx

formation. If the valve does not open enough, insufficient
re-circulation takes place and excess pollution is created.
If, however, the valve sticks open, the temperature inside
the cylinder can drop too much, decreasing engine
performance and fuel mileage. Krytox™ lubricants are an
ideal choice, as they withstand the high temperaturesand exhaust fumes experienced by the EGR valve.
Spark Plug Boots
The spark plug boot protects the spark plug fromweather and prevents the unintentional grounding of thespark energy.
The boot is made of a silicone rubber, which, over time,
can bond with the silicon ceramic of the spark plug,
fusing the boot and the spark plug together. Once thisoccurs, the only way to remove the boot is by force,
which can cause enough damage to require replacementof the entire assembly. Krytox™ lubricants can prevent
this fusion from taking place. Krytox™ lubricants are
ideal in this application because they are stable, nonreactive, and long-lasting. They can also withstandthe high temperatures and energies of the spark plug
environment.
